Object oriented database and electronic notebook for transmission electron microscopy.

As high-resolution biological transmission electron microscopy (TEM) has increased in popularity over recent years, the volume of data and number of projects underway has risen dramatically. A robust tool for effective data management is essential to efficiently process large data sets and extract maximum information from the available data. We present the Electron Microscopy Electronic Notebook (EMEN), a portable, object-oriented, web-based tool for TEM data archival and project management. EMEN has several unique features. First, the database is logically organized and annotated so multiple collaborators at different geographical locations can easily access and interpret the data without assistance. Second, the database was designed to provide flexibility to the user, so it can be used much as a lab notebook would be, while maintaining a structure suitable for data mining and direct interaction with data-processing software. Finally, as an object-oriented database, the database structure is dynamic and can be easily extended to incorporate information not defined in the original database specification.

An ergonomic evaluation comparing desktop, notebook, and subnotebook computers.

OBJECTIVE: To evaluate and compare the postures and movements of the cervical and upper thoracic spine, the typing performance, and workstation ergonomic factors when using a desktop, notebook, and subnotebook computers. DESIGN: Repeated-measures design. SETTING: A motion analysis laboratory with an electromagnetic tracking device. PARTICIPANTS: A convenience sample of 21 university students between ages 20 and 24 years with no history of neck or shoulder discomfort. INTERVENTION: Each subject performed a standardized typing task by using each of the 3 computers. MAIN OUTCOME MEASURES: Measurements during the typing task were taken at set intervals. RESULTS: Cervical and thoracic spines adopted a more flexed posture in using the smaller-sized computers. There were significantly greater neck movements in using desktop computers when compared with the notebook and subnotebook computers. The viewing distances adopted by the subjects decreased as the computer size decreased. Typing performance and subjective rating of difficulty in using the keyboards were also significantly different among the 3 types of computers. CONCLUSIONS: Computer users need to consider the posture of the spine and potential risk of developing musculoskeletal discomfort in choosing computers.

NeuroScholar's electronic laboratory notebook and its application to neuroendocrinology.

Scientists continually relate information from the published literature to their current research. The challenge of this essential and time-consuming activity increases as the body of scientific literature continues to grow. In an attempt to lessen the challenge, we have developed an Electronic Laboratory Notebook (ELN) application. Our ELN functions as a component of another application we have developed, an open-source knowledge management system for the neuroscientific literature called NeuroScholar (http://www. neuroscholar. org/). Scanned notebook pages, images, and data files are entered into the ELN, where they can be annotated, organized, and linked to similarly annotated excerpts from the published literature within Neuroscholar. Associations between these knowledge constructs are created within a dynamic node-and-edge user interface. To produce an interactive, adaptable knowledge base. We demonstrate the ELN's utility by using it to organize data and literature related to our studies of the neuroendocrine hypothalamic paraventricular nucleus (PVH). We also discuss how the ELN could be applied to model other neuroendocrine systems; as an example we look at the role of PVH stressor-responsive neurons in the context of their involvement in the suppression of reproductive function. We present this application to the community as open-source software and invite contributions to its development.

Interacting with notebook input devices: an analysis of motor performance and users' expertise.

In the present study the usability of two different types of notebook input devices was examined. The independent variables were input device (touchpad vs. mini-joystick) and user expertise (expert vs. novice state). There were 30 participants, of whom 15 were touchpad experts and the other 15 were mini-joystick experts. The experimental tasks were a point-click task (Experiment 1) and a point-drag-drop task (Experiment 2). Dependent variables were the time and accuracy of cursor control. To assess carryover effects, we had the participants complete both experiments, using not only the input device for which they were experts but also the device for which they were novices. Results showed the touchpad performance to be clearly superior to mini-joystick performance. Overall, experts showed better performance than did novices. The significant interaction of input device and expertise showed that the use of an unknown device is difficult, but only for touchpad experts, who were remarkably slower and less accurate when using a mini-joystick. Actual and potential applications of this research include an evaluation of current notebook input devices. The outcomes allow ergonomic guidelines to be derived for optimized usage and design of the mini-joystick and touchpad devices.

A single case experimental design comparing two memory notebook formats for a man with memory problems caused by traumatic brain injury.

There is extensive literature demonstrating that restoration of memory is not a realistic goal for rehabilitation and that efforts are more effective if focused on developing compensatory strategies. This paper compares two formats of memory notebook using an ABAB single-case experimental design with a 46-year-old man with a history of head injury. Results revealed significantly better performance on a series of prospective memory tasks for the "modified" notebook. The study highlights the importance of tailoring the diary to the patient's needs and giving careful consideration to the way in which the diary is introduced.

The status of electronic laboratory notebooks for chemistry and biology.

Documenting an experiment in a way that ensures that the record can act as evidence to support a patent claim or to demonstrate compliance with the US Food and Drug Administration's (FDA's) predicate rules, puts demands on an electronic laboratory notebook (ELN) that are not trivial. The 1996 General Agreement on Tariffs and Trade (GATT) allowed notebook records that were generated outside of the US to be used to claim precedence in US patent claims. This agreement spurred interest in the development of ELNs in Europe. The pharmaceutical research process became dependent on computer systems during the latter part of the 1990s, and this also led to a wider interest in ELNs. More recently, the FDA began to encourage submissions in an all-electronic form, leading to great interest in the use of ELNs in development and manufacturing. As a result of these influences, the pharmaceutical industry is now actively pursuing ELN evaluations and implementations. This article describes some of the early efforts and the recent drivers for ELN adoption. The state of the ELN market in 2005 is also described.

A Virtual Notebook for biomedical work groups.

During the past several years, Baylor College of Medicine has made a substantial commitment to the use of information technology in support of its corporate and academic programs. The concept of an Integrated Academic Information Management System (IAIMS) has proved central in our planning, and the IAIMS activities that we have undertaken with funding from the National Library of Medicine have proved to be important extensions of our technology development. Here we describe our Virtual Notebook system, a conceptual and technologic framework for task coordination and information management in biomedical work groups. When fully developed and deployed, the Virtual Notebook will improve the functioning of basic and clinical research groups in the college, and it currently serves as a model for the longer-term development of our entire information management environment.

Use of notebook computers for third-year surgical students.

BACKGROUND: Computer-aided instruction has become increasingly popular in medical education. Notebook computers (NCs) are attractive, convenient microcomputers. We hypothesized that use of NCs by third-year surgical students would enhance their performance of educational activities. METHODS: During the 1994-1995 academic year 25 student volunteers used NCs during the surgery clerkship. NC software included questions for self-examination, anatomy self-instruction program, word processing and electronic mail (e-mail) for recording and sending history and physicals (H & Ps) to faculty for review, and MEDLINE search software. Identical software was available to all students at on-campus computer centers. All students were asked to record the number of hours that they used the self-examination and anatomy programs, number of H & Ps performed and reviewed by faculty, and number of literature searches performed. NC users were interviewed regarding the value of NC use and their rating of software programs. RESULTS: NC users (n = 25) used the self-examination and anatomy programs more often, performed more literature searches, and had a greater percentage of their H & Ps reviewed by faculty compared with non-NC users (n = 143) (p < 0.05 for all outcomes). Most NC users agreed that NC use was enjoyable and valuable, and they believed that all students should have NCs during the surgery clerkship. Students rated software in order of preference: e-mail > self-examination > MEDLINE search > anatomy program. CONCLUSIONS: NC use enhanced performance of educational activities in the surgery clerkship. Effort toward developing educational software for surgical students is warranted because students are likely to use such programs.

Automated smear counting and data processing using a notebook computer in a biomedical research facility.

An automated smear counting and data processing system for a life science laboratory was developed to facilitate routine surveys and eliminate human errors by using a notebook computer. This system was composed of a personal computer, a liquid scintillation counter and a well-type NaI(Tl) scintillation counter. The radioactivity of smear samples was automatically measured by these counters. The personal computer received raw signals from the counters through an interface of RS-232C. The software for the computer evaluated the surface density of each radioisotope and printed out that value along with other items as a report. The software was programmed in Pascal language. This system was successfully applied to routine surveys for contamination in our facility.

Delivering health information about self-medication to older adults: use of touchscreen-equipped notebook computers.

Preventing Drug Interactions in Active Older Adults is an educational intervention to prevent prescription and over-the-counter (OTC) drug and alcohol interactions in active, community-living older adults. The objectives of the program are to increase older adults' knowledge of potential interactions of prescription medications with OTC drugs and alcohol and to increase their confidence (self-efficacy) about how to avoid such interactions. An interactive multimedia computer software program (Personal Education Program or PEP) was designed for the learning styles and psychomotor skills of older adults. Focus groups of older adults evaluated PEP components in a formative manner during development. The program content dealing with antacids, calcium supplements, and acid reducers was pilot tested with 60 older adults recruited from local senior centers. Participants used the PEP on notebook computers equipped with infrared-sensitive touchscreens. Users of PEP had greater knowledge and self-efficacy scores than controls. Participants indicated a high degree of satisfaction with the PEP and reported their intent to make specific changes in self-medication behaviors.

On Darwin's 'metaphysical notebooks'. I: teleology and the project of a theory.

Huxley's essay On the Reception of the 'Origin of Species' brings us close to the issue of cause and of why- and how-questions in the understanding of the living world. The present contribution, which is divided into two parts, reviews the problem of Teleology as conceived by Huxley and re-examines Darwin as the author who revealed the existence of a 'foundations problem' in the explanation of an entire realm of nature, i.e., the problem of explaining such realm in terms of its own, specific legality, or iuxta sua propria principia. In the first part the enquiry is mainly focused on the secularization of natural history after Paley; in the second part it is mainly focused on the desubjectivization of the inquiry into natural history after Erasmus Darwin and Lamarck. The second part will be published in the next issue of Rivista di Biologia/Biology Forum. In the first part below an analysis is made of Notebooks M and N. The author disputes the correctness of conceiving them only as the works where Darwin envisages the 'metaphysical' themes later to become the subject of The Expression of the Emotions. He suggests to conceive of them also as the works where Darwin defines the terms of the general project of his own, peculiar evolutionary theory. The author then outlines the intellectual progress of Darwin from the inosculation to the transmutation hypotheses. Darwin's reading of Malthus appears to be analytically decisive, because it offers him the vintage point to attack the metaphysical and theological citadels on the morphological side. Darwin is thus able to re-consider Erasmus' comprehensive zoonomic project, by displacing it, however, from the old idea of the scala naturae to the new one of the "coral of life", and by emphasising the distinction between "the fittest" and "the best" vs. the tradition of Natural Theology.

On Darwin's 'metaphysical notebooks'. II: "Metaphysics" and final cause.

The first part of this paper was published in Rivista di Biologia/Biology Forum 94 (2001). In the second part below an examination is made of the meaning of the term Metaphysics in some passages of the Darwinian Notebooks for the years 1836-1844. Metaphysics no longer defines a field of philosophical enquiries mainly concerning the being and the essence after the manner of Aristotle; it now refers to a kind of philosophy of mind after the manner of J. Locke's criticism of the Hypokeimenon. However Aristotle's Metaphysics also encompasses a treatment of the idea of causes, and of final cause particularly, in the explanation of events, and in the explanation of natural phenomena especially. The criticism of the idea of final cause in the interpretation of the world of life is one of Darwin's foundational acts in his early years. When conceiving his Système du monde, in the last years of the XVIII Century, Laplace could think that God is a hypothesis not really needed by science, as we are told. For the knowledge of organic nature to attain the status of science, it remained to be shown that since--certain of the exemplariness of Newton's Principles as much as cautious before the mystery of life--did not need the hypothesis of final ends in order to understand and explain the productions of the living nature: not only in the form of that final cause (the First Cause, the Vera Causa) in which Natural Theology still rested, but also in the form of nature's inner finality which still moulded Whewell's Kantian philosophy. Such demonstration is a very important subject in Darwin's early enquiries, where he criticises finalism as a projection of self-conceiving Man, likely inherited from a knowing of causality in nuce to be found also in animals.

[Anatomical observations in Spallanzani's laboratory notebooks].

As though embarrassed by the huge amount of material he stored up, Spallanzani hid entire parts of his biological project. A good example is given by 25 laboratory notebooks which were to constitute the basis of a major work on regeneration he announced in the year 1768 and never published. There Spallanzani recorded anatomical observations he carried out on some annelids with a refinement of method and critical understanding only equalled by Malpighi and Lyonnet when observing caterpillars. His research on these organisms highlights how critically Spallanzani referred to the various versions of the generally accepted principle of the uniformity of composition of animal structure.

[Freud's patient notebooks. Seventeen analysts in analysis with Freud (1910-1920)].

The author examines the course of 17 analyses, as conducted by Freud, on the basis of a new source, Freud's patient notebooks. All analysands (5 women, 12 men) were or were to become members of a psychoanalytic society. Their treatments were marked by a relatively short duration (all of them less than one year) and a very high number of hours per week (generally 6). The total number of hours ranged between 9 and about 250. Compared to present conditions, both the duration and the number of weekly hours show the great historical change that has taken place. The author discusses this change as well as some other characteristics, e. g. the customary extra-analytical contact between Freud and his analysands. In an appendix, treatment profiles of all 17 analyses are given, summarizing their duration, the total number of hours, number of hours per week and number of hours in each month of treatment.
